Description

本発明は、筋の老化防止用組成物に関するものである。   The present invention relates to a composition for preventing muscle aging.

近年、加齢に伴う筋力の低下および筋肉量の減少を「サルコペニア」とよび、寝たきりに関与するものとして非常に注目されている。サルコペニアには加齢に伴って変化する身体活動の低下の他、栄養摂取量、ホルモン、炎症反応など様々な要因が関与すると言われており、80歳以上では50%以上が罹患していると推計される。サルコペニアが生じると、易転倒・転落、骨折、体動制限そしてサルコペニアの進行という悪循環を呈し、寝たきり状態を誘発する。70歳以上でサルコペニアを合併している場合、合併していない場合と比べて死亡率は2.3倍になるという報告もある。厚生白書によると、日本では2025年には寝たきりの高齢者が230万人に達すると推計されており、サルコペニアの予防や治療は重要な課題である。   In recent years, a decrease in muscle strength and a decrease in muscle mass associated with aging is called “sarcopenia” and has attracted much attention as being related to bedridden. It is said that sarcopenia is associated with various factors such as nutritional intake, hormones, and inflammatory response in addition to the decline in physical activity that changes with age. Estimated. When sarcopenia occurs, it causes a vicious circle of easy falls / falls, fractures, body movement limitations, and progression of sarcopenia, and induces a bedridden state. There is a report that mortality rate is 2.3 times higher when sarcopenia is merged at the age of 70 or more than when not merging. According to the welfare white paper, it is estimated that the number of bedridden elderly people will reach 2.3 million in 2025 in Japan, and prevention and treatment of sarcopenia is an important issue.

現在、サルコペニアの予防および治療において、最も有効な手段は筋力トレーニングであるが(非特許文献1、2)、関節や循環器などの合併症を持つ高齢者や、既に体動制限を余儀なくされたりしている高齢者に対して、必要十分な強度の運動介入は困難である。サルコペニアの予防および治療薬として、必須アミノ酸、ホルモン剤(テストステロン、エストロゲン、成長ホルモン)、ACE阻害剤の臨床研究がなされているが、アミノ酸は治療効果がなく(非特許文献3)、ホルモン剤は乳がんや前立腺がん等のリスクが上がり、ACE阻害剤は症例が少なくエビデンス構築に至らないと報告されている(非特許文献4)。つまり、現在のところサルコペニアに対して十分な対策が行われていない状況であり、その治療薬として承認されている薬剤は皆無である。   Currently, muscle training is the most effective means for prevention and treatment of sarcopenia (Non-patent Documents 1 and 2), but elderly people with complications such as joints and circulatory organs, and body movement restrictions have already been forced. It is difficult for the elderly who are engaged in exercise intervention with sufficient and sufficient intensity. As a prophylactic and therapeutic agent for sarcopenia, clinical studies have been conducted on essential amino acids, hormone agents (testosterone, estrogen, growth hormone), and ACE inhibitors, but amino acids have no therapeutic effect (Non-patent Document 3). It has been reported that the risk of breast cancer, prostate cancer, etc. is increased, and ACE inhibitors have few cases and do not lead to evidence construction (Non-patent Document 4). In other words, at present, sufficient measures have not been taken against sarcopenia, and there is no drug approved as a therapeutic drug.

(3-2)食事摂取量
1週間の食事摂取量を測定し、各群の1日1匹当たりの食事摂取量を算出した。結果を図2に示した。SAMRとSAMP8との間に食事摂取量の差は認められなかった。また、SAMRおよびSAMP8ともに、牛車腎気丸群の方が普通食群より食事摂取量が少ない傾向が認められたが、牛車腎気丸群と普通食群との間に有意差はなかった。
(3) Results (3-1) Body weight Changes in the average body weight of each group at the age of 8 weeks and the average body weight of each group at the age of 38 weeks are shown in FIG. The weight gain of SAMP8 was significantly lower than the weight gain of SAMR. However, at 38 weeks of age, both the SAMR and SAMP8 showed a tendency for the average weight to be heavier in the Ushazama Kigan test group than in the normal diet group. There was no difference.
(3-2) Food intake The food intake per week was measured, and the daily food intake per animal in each group was calculated. The results are shown in FIG. There was no difference in dietary intake between SAMR and SAMP8. In addition, in both the SAMR and the SAMP8, the ox cart kidney testicle group tended to have less food intake than the normal diet group, but there was no significant difference between the ox cart kidney test group and the regular diet group.

(3-3) Image of Soleus Muscle Stained with Hematoxylin and Eosin FIG. 3 shows an image of soleus muscle stained with hematoxylin and eosin. The upper part is SAMR and the lower part is SAMP8. The left side is the normal food group, and the right side is the ox cart kidney group. In the lower left SAMP8 normal diet group of the soleus muscle, the progression of muscle atrophy was observed as compared with the upper SAMR soleus muscle. On the other hand, it was confirmed that the muscle atrophy was clearly improved in the soleus muscle of the mouse in the lower right SAMP8 oxcart nephricle group.
(3-4) Muscle Fiber Area The measurement results of the muscle fiber area of the soleus muscle of each group are shown in FIG. In the figure, * indicates that there is a significant difference at P <0.0001.

It has been shown.

(3-5)小括
SAMP8普通食群においてヒラメ筋の筋萎縮の進行が観察されたことから、従来老化促進モデルマウスとして使用されてきたSAMP8は、サルコペニアモデルマウスとして適切であることが明らかとなった。SAMP8牛車腎気丸群では、ヒラメ筋の筋萎縮が抑制されることが観察された。一方、SAMP8の普通食群と牛車腎気丸群の体重および食事摂取量に差がなかったことから、牛車腎気丸の薬効が直接的に筋肉の委縮を改善させたものと考えられた。すなわち、以上の結果から、牛車腎気丸投与に起因して食事摂取量が増加し、活動量が上がり、筋肉量が増加(体重が増加)した結果、筋萎縮が抑制されたのではないことが示された。
(3-5) Summary Since the progression of soleus muscle atrophy was observed in the SAMP8 normal diet group, it was clear that SAMP8, which had been used as an aging promoting model mouse, was suitable as a sarcopenia model mouse. became. It was observed that in the SAMP8 oxcart nephricle group, muscle atrophy of the soleus was suppressed. On the other hand, since there was no difference in the body weight and dietary intake between the normal diet group of SAMP8 and the oxcart kidney testicle group, it was considered that the medicinal effect of oxcart kidney testicle directly improved muscle atrophy. That is, from the above results, it is not that muscle atrophy was suppressed as a result of increased dietary intake, increased activity, and increased muscle mass (weight gain) due to administration of Goshajinkigan It has been shown.

(3-6)遅筋(トロポニンI)および速筋(トロポニンT)の解析
サルコペニアでは速筋が減少し遅筋が増加することが知られている。そこで、免疫染色によりヒラメ筋標本の遅筋(トロポニンI陽性)および速筋(トロポニンT陽性)を染め分けた。結果を図5に示した。図中濃く染まっているのが遅筋、薄く染まっているのが速筋である。図5から明らかなように、SAMP8普通食群では遅筋の量が増加していたが、SAMP8牛車腎気丸群では遅筋の量が減少しており、SAMRと同等であった。
各群のマウスの筋肉中のトロポニンIおよびトロポニンTの発現量をウエスタンブロッティングで解析した結果を図6に示した。図6から明らかなように、SAMP8普通食群ではトロポニンIの発現量が増加し、トロポニンTの発現量が減少していたが、SAMP8牛車腎気丸群では普通食群よりトロポニンIの発現量が減少し、ロポニンTの発現量が増加していた。この結果は、上記の免疫染色の結果と一致した。
(3-6) Analysis of slow muscle (troponin I) and fast muscle (troponin T) In sarcopenia, it is known that fast muscle decreases and slow muscle increases. Therefore, the slow muscle (troponin I positive) and fast muscle (troponin T positive) of the soleus muscle specimen were dyed separately by immunostaining. The results are shown in FIG. In the figure, the slow muscle is dyed darkly, and the fast muscle is dyed lightly. As is clear from FIG. 5, the amount of slow muscle was increased in the SAMP8 normal diet group, but the amount of slow muscle was decreased in the SAMP8 oxcart nephricle group, which was equivalent to SAMR.
The results of analyzing the expression levels of troponin I and troponin T in the muscle of each group of mice by Western blotting are shown in FIG. As is apparent from FIG. 6, the expression level of troponin I increased and the expression level of troponin T decreased in the SAMP8 normal diet group, but the expression level of troponin I in the SAMP8 oxcart nephrology group than in the normal food group. Decreased, and the expression level of loponin T was increased. This result was consistent with the above immunostaining results.

(3-7)筋肉中のPGC−1α発現量の解析
筋線維の強さは、生理範囲内におけるPGC−1α発現量に依存することが知られている(参考文献:Lin J et al. Transcriptional co-activator PGC-1 alpha drives the formation of slow-twitch muscle fibers. Nature. 2002 Aug 15;418(6899):797-801.)。そこで、各群のマウスの筋肉中のPGC−1αの発現量をウエスタンブロッティングで解析した。結果を図7に示した。図7から明らかなように、SAMP8普通食群ではPGC−1αの発現量が減少していたが、SAMP8牛車腎気丸群ではPGC−1αの発現量が増加しており、SAMRと同等であった。
(3-7) Analysis of expression level of PGC-1α in muscle It is known that the strength of muscle fiber depends on the expression level of PGC-1α in the physiological range (reference: Lin J et al. Transcriptional co-activator PGC-1 alpha drives the formation of slow-twitch muscle fibers. Nature. 2002 Aug 15; 418 (6899): 797-801.). Therefore, the expression level of PGC-1α in the muscle of each group of mice was analyzed by Western blotting. The results are shown in FIG. As is clear from FIG. 7, the expression level of PGC-1α was decreased in the SAMP8 normal diet group, but the expression level of PGC-1α was increased in the SAMP8 oxcart kidney testicle group, which was equivalent to SAMR. It was.

(3-8)筋肉中のAktのリン酸化の解析
セリン・スレオニンキナーゼであるAktは、Thr308およびSer473の2つのアミノ酸がリン酸化されることにより活性化され、このAktのシグナルが筋肉の量と質量を規定することが知れている(参考文献:Baumgartner RN et al.Predictors of skeletal muscle mass in elderly men and women.Mech Ageing Dev. 1999 Mar 1;107(2):123-36.、Roubenoff R, Hughes VA.Sarcopenia: current concepts.J Gerontol A Biol Sci Med Sci. 2000 Dec;55(12):M716-24.)。そこで、各群のマウスの筋肉中のAktのリン酸化をウエスタンブロッティングで解析した。結果を図8に示した。図8から明らかなように、SAMP8普通食群では、Aktの発現量は他の群と同等であるが、Thr308のリン酸化とSer473のリン酸化が減弱していた。一方、SAMP8牛車腎気丸群ではThr308およびSer473のリン酸化がSAMRと同等レベルに回復していた。
(3-8) Analysis of phosphorylation of Akt in muscle Akt, a serine / threonine kinase, is activated by phosphorylation of two amino acids, Thr308 and Ser473, and this Akt signal is correlated with the amount of muscle. It is known to regulate mass (reference: Baumgartner RN et al. Predictors of skeletal muscle mass in elderly men and women. Mech Aging Dev. 1999 Mar 1; 107 (2): 123-36., Roubenoff R, Hughes VA. Sarcopenia: current concepts. J Gerontol A Biol Sci Med Sci. 2000 Dec; 55 (12): M716-24.). Therefore, phosphorylation of Akt in the muscle of each group of mice was analyzed by Western blotting. The results are shown in FIG. As is clear from FIG. 8, in the SAMP8 normal diet group, the expression level of Akt was the same as in the other groups, but phosphorylation of Thr308 and phosphorylation of Ser473 were attenuated. On the other hand, phosphorylation of Thr308 and Ser473 recovered to the same level as SAMR in the SAMP8 ox cart.

(3-9)筋肉中のGSK3βのリン酸化の解析
筋肉においては、Aktシグナルの下流に、グリコーゲン合成を促進するGSK3βが存在する。そこで、各群のマウスの筋肉中のGSK3βのリン酸化をウエスタンブロッティングで解析した。結果を図9に示した。図9から明らかなように、SAMP8普通食群では、GSK3βの発現量は他の群と同等であるが、Ser9のリン酸化が減弱していた。一方、SAMP8牛車腎気丸群ではSer9のリン酸化がSAMRと同等レベルに回復していた。
(3-9) Analysis of phosphorylation of GSK3β in muscle In muscle, GSK3β that promotes glycogen synthesis exists downstream of the Akt signal. Therefore, the phosphorylation of GSK3β in the muscle of each group of mice was analyzed by Western blotting. The results are shown in FIG. As is clear from FIG. 9, in the SAMP8 normal diet group, the expression level of GSK3β was the same as in the other groups, but Ser9 phosphorylation was attenuated. On the other hand, Ser9 phosphorylation was restored to the same level as SAMR in the SAMP8 ox cart.

(3-10)PAS染色による筋肉中のグリコーゲン染色
各群のマウスのヒラメ筋の組織標本をPAS染色した結果を図10に示した。図中、濃く染まっているのがグリコーゲンである。図10から明らかなように、SAMP8普通食群ではグリコーゲンがほとんど染まっていないが、SAMP8牛車腎気丸群では劇的にグリコーゲン量が改善しており、加齢による筋肉のグリコーゲン貯蔵機能の低下が改善していることが示された。
(3-10) Glycogen staining in muscle by PAS staining FIG. 10 shows the result of PAS staining of a tissue specimen of soleus muscle of each group of mice. In the figure, glycogen is darkly stained. As is apparent from FIG. 10, glycogen is hardly stained in the SAMP8 normal diet group, but the amount of glycogen is dramatically improved in the SAMP8 oxshakigan group, and the decrease in muscle glycogen storage function due to aging is evident. It was shown that it was improving.

(3-11)筋肉中のFoxOファミリーのリン酸化の解析
Aktシグナルのもう一つの下流にFoxOファミリーが存在する。Aktシグナルにより、FoxOファミリーのリン酸化が減弱されると、筋萎縮につながることが報告されている(参考文献:Machida S et al. Forkhead transcription factor FoxO1 transduces insulin-like growth factor's signal to p27Kip1 in primary skeletal muscle satellite cells. J Cell Physiol. 2003 Sep;196(3):523-31.、Kamei Y et al. Skeletal muscle FOXO1 (FKHR) transgenic mice have less skeletal muscle mass, down-regulated Type I (slow twitch/red muscle) fiber genes, and impaired glycemic control. J Biol Chem. 2004 Sep 24;279(39):41114-23.)。そこで、各群のマウスの筋肉中のFoxOファミリーのリン酸化をウエスタンブロッティングで解析した。
結果を図11に示した。図11から明らかなように、SAMP8普通食群では、FoxO1のSer256およびFoxO3aSer253のリン酸化は、他の群とほぼ同等のレベルであったが、FoxO4のSer193のリン酸化が減弱していた。一方、SAMP8牛車腎気丸群ではSer193のリン酸化がSAMRと同等レベルに回復していた。
(3-11) Analysis of phosphorylation of FoxO family in muscle FoxO family exists in the other downstream of Akt signal. It has been reported that when the phosphorylation of FoxO family is attenuated by Akt signal, it leads to muscle atrophy (reference: Machida S et al. Forkhead transcription factor FoxO1 transduces insulin-like growth factor's signal to p27Kip1 in primary skeletal J Cell Physiol. 2003 Sep; 196 (3): 523-31., Kamei Y et al. Skeletal muscle FOXO1 (FKHR) transgenic mice have less skeletal muscle mass, down-regulated Type I (slow twitch / red muscle) fiber genes, and impaired glycemic control. J Biol Chem. 2004 Sep 24; 279 (39): 41114-23.). Thus, FoxO family phosphorylation in the muscle of each group of mice was analyzed by Western blotting.
The results are shown in FIG. As is clear from FIG. 11, phosphorylation of FoxO1 Ser256 and FoxO3aSer253 in the SAMP8 normal diet group was almost the same level as other groups, but phosphorylation of SerO of FoxO4 was attenuated. On the other hand, Ser193 phosphorylation was restored to the same level as SAMR in the SAMP8 ox cart.

(3-12)筋肉中のMAFbxおよびMuRF1発現量の解析
FoxOファミリーは、さらに下流のAtrogin−1/MAFbxとMuRF1を増加させ、筋萎縮を進行させると報告されている(参考文献:Clavel S et al.Atrophy-related ubiquitin ligases, atrogin-1 and MuRF1 are up-regulated in aged rat Tibialis Anterior muscle. Mech Ageing Dev. 2006 Oct;127(10):794-801.、Bodine SC et al.Identification of ubiquitin ligases required for skeletal muscle atrophy.Science. 2001 Nov 23;294(5547):1704-8. Epub 2001 Oct 25.)。そこで、各群のマウスの筋肉中のMAFbxおよびMuRF1の発現量をウエスタンブロッティングで解析した。結果を図12に示した。図12から明らかなように、SAMP8普通食群ではMuRF1の発現量が増強されていたが、SAMP8牛車腎気丸群ではMuRF1の発現量が、SAMRと同等レベルに正常化されていた。
(3-12) Analysis of expression levels of MAFbx and MuRF1 in muscle The FoxO family has been reported to further increase downstream Atrogin-1 / MAFbx and MuRF1 to promote muscle atrophy (Reference: Clavel Set et al. al.Atrophy-related ubiquitin ligases, atrogin-1 and MuRF1 are up-regulated in aged rat Tibialis Anterior muscle.Mech Aging Dev. 2006 Oct; 127 (10): 794-801., Bodine SC et al.Identification of ubiquitin ligases required for skeletal muscle atrophy. Science. 2001 Nov 23; 294 (5547): 1704-8. Epub 2001 Oct 25.). Therefore, the expression levels of MAFbx and MuRF1 in the muscle of each group of mice were analyzed by Western blotting. The results are shown in FIG. As is clear from FIG. 12, the expression level of MuRF1 was enhanced in the SAMP8 normal diet group, whereas the expression level of MuRF1 was normalized to a level equivalent to that of SAMR in the SAMP8 oxcart.

(4)考察
以上より、牛車腎気丸に含まれるいずれかの成分が老化によるAktの細胞内シグナルの減弱を正常化し、その下流であるグリコーゲン合成に関わるGSK3βのリン酸化を改善する。同時に筋萎縮に関わるFoxOファミリーの中で、FoxO4のSer193のリン酸化を改善し、MuRF1の発現量を正常化し、サルコペニアを予防または治療できると考えられた。また、PGC−1α発現量を正常化することも、サルコペニアの予防または治療につながると考えられた。
(4) Consideration As described above, any component contained in Goshajinkigan makes normal attenuation of Akt intracellular signal due to aging, and improves phosphorylation of GSK3β related to glycogen synthesis downstream thereof. At the same time, in the FoxO family involved in muscle atrophy, it was considered that the Ser193 phosphorylation of FoxO4 was improved, the expression level of MuRF1 was normalized, and sarcopenia could be prevented or treated. Moreover, normalizing the expression level of PGC-1α was considered to lead to the prevention or treatment of sarcopenia.

As is clear from FIG. 13 and FIG. 14, it was shown that all Chinese herbal supplements suppress the progression of sarcopenia in senescence-accelerated model mice. The degree of suppression was Oxshaki Kikimaru>Hachimimaru> Rokumimaru. Similar to the results of Example 1, the muscle fiber area of the oxcart nephricle group was equivalent to SAMR.

〔実施例3:牛車腎気丸の抗サルコペニア効果の臨床的検討〕
(1)対象
大阪府内のクリニックにおいて2013年8月から12月までに、筋力低下を自覚し、牛車腎気丸内服を希望し、ロコモ度テストにボランティアとして協力した8名の患者を対象とした。
[Example 3: Clinical study of anti-sarcopenia effect of oxcart nephrology]
(1) Subjects Targeting 8 patients who were aware of muscular weakness, hoped to be oxcart kidney kimaru, and cooperated as a volunteer for the locomotive degree test from August to December 2013 at a clinic in Osaka Prefecture. .

(2)方法
平成25年5月27日に公益社団法人日本整形外科学会ロコモチャレンジ!推進協議会が発表した「ロコモ度テスト」(将来ロコモティブシンドロームになり得る可能性を判定する方法)をベースに、以下の6項目の評価を行った。牛車腎気丸投与開始前に最初の評価を行い、外来受診の状況に応じて2〜3か月目に再評価を行った。牛車腎気丸投与開始前および牛車腎気丸治療後の各項目について平均値および標準偏差を算出し、paired t−testにより統計評価を行った。なお、ロコモチャレンジではロコモーショントレーニングを推奨しているが、今回は薬剤の効果を判定することが目的であるため、運動の指導は行わなかった。
(2) Method The Japanese Orthopedic Association Locomo Challenge on May 27, 2013! Based on the “locomo degree test” announced by the Promotion Council (a method to determine the possibility of becoming a future locomotive syndrome), the following six items were evaluated. The first evaluation was performed before the start of the Oxcart nephrology administration, and re-evaluation was performed in 2 to 3 months depending on the situation of the outpatient visit. An average value and a standard deviation were calculated for each item before the start of oxcart kidney testicles and after treatment with oxcart kidney testicles, and statistical evaluation was performed by paired t-test. Locomo Challenge recommends Locomotion training, but this time the purpose was to determine the effect of the drug, so exercise guidance was not provided.

(3)評価項目
1.身長、体重、BMI
2.筋量、脂肪量(いずれもTANITA製マルチ周波数体組成計MC−980Aを用いて測定)
3.両手の握力測定
4.立ち上がりテスト(下肢筋力の強さを判定)
5.2ステップテスト(歩幅を図ることで歩行能力を判定)
6.ロコモ25(25の質問により身体状態、生活状況を評価する。身体における痛みや動かしにくさに加え、生活積極度についてもチェックし、運動器の身体状態と生活状態に不自由なことが生じる可能性を点数化し、将来ロコモになる危険度を判定する。)
(3) Evaluation items Height, weight, BMI
2. Muscle mass and fat mass (both measured using a multi-frequency body composition meter MC-980A manufactured by TANITA)
3. 3. Measurement of grip strength of both hands Stand-up test (determines strength of lower limb muscle strength)
5.2 step test (walking ability is determined by stride)
6). Locomo 25 (Evaluate body condition and living situation by 25 questions. In addition to pain and inability to move in the body, check the degree of active life, and there may be inconvenience in the physical state and living state of the exercise equipment. (Determine the risk of becoming a locomotive in the future.)

「立ち上がりテスト」の方法は以下のとおりである。10、20、30および40cmの台を用意する。まず40cmの台に両腕を組んで腰かけ、両脚を肩幅くらいに広げ、床に対して脛がおよそ70度になるようにして、反動をつけずに立ち上がり、そのまま3秒間保持する。40cmの台から両脚で立ち上がれた場合、次に片脚でテストをする。初めの姿勢に戻り、左右どちらかの脚を上げ、反動をつけずに立ち上がり、3秒間保持できれば成功とする。左右ともに片脚で立ち上がることができれば成功とする。次に、10cmずつ低い台に移り、同様のテストを繰り返す。   The method of “rise test” is as follows. Prepare a 10, 20, 30 and 40 cm platform. First, sit down with your arms crossed on a 40 cm base, spread your legs to the shoulder width, stand up to the floor with the shin at approximately 70 degrees, and keep it standing for 3 seconds. If you get up on both legs from a 40cm stand, then test with one leg. Return to the initial position, raise either leg on the left, stand up without recoil, and hold for 3 seconds. If you can stand up with one leg on both the left and right, it will be a success. Next, move to a base 10 cm lower and repeat the same test.

「2ステップテスト」の方法は以下のとおりである。スタートラインを決め、両足のつま先を合わせ、できる限り大股で2歩歩き、両足を揃える。バランスをくずした場合は失敗とする。最初に立ったラインから、着地点のつま先までを測定する。2回行ってよかったほうの記録を採用する。以下の計算式で2ステップ値を算出する。
2ステップ値=2歩幅(cm)÷身長(cm)
The method of “two-step test” is as follows. Determine the starting line, match the toes of both feet, walk as long as possible with two legs and align both feet. If the balance is lost, it will fail. Measure from the first standing line to the toe of the landing point. Adopt the record that was good to go twice. The 2-step value is calculated using the following formula.
2 step value = 2 steps (cm) ÷ height (cm)

(3)評価結果
(3-1)患者背景
患者背景を図15に示した。女性8人、各項目の平均値および標準偏差は、年齢62.3±10.3歳、身長159.0±5.6cm、体重54.6±7.3kg、BMI21.5±1.84、牛車腎気丸の平均投与期間は77.3±29.7日であった。
(3) Evaluation results (3-1) Patient background The patient background is shown in FIG. Eight women, mean and standard deviation of each item are age 62.3 ± 10.3 years old, height 159.0 ± 5.6 cm, weight 54.6 ± 7.3 kg, BMI 21.5 ± 1.84, The average administration period of Goshajinkigan was 77.3 ± 29.7 days.

(3-2)開始時の評価
握力は、右が20.3±6.5kg、左が20.6±5.7kgであった。立ち上がりテストは、片足ができなかった患者が3人、40cmが可能であった患者が4人、10cmが1人であった。40〜60代の女性は、目安として40cmを片足で立ちあがれるとされていることから、対象患者は脚力がやや低下していると考えられた。2ステップ値は1.28±0.2であり、40〜60代の女性の平均値が1.45〜1.49であることから、対象患者は移動能力がやや低下していると考えられた。ロコモ25は10.3±10.8点であり、個人差が大きかった。
(3-2) Evaluation at the start The grip strength on the right was 20.3 ± 6.5 kg and on the left was 20.6 ± 5.7 kg. In the standing-up test, there were 3 patients who could not have one leg, 4 patients who could be 40 cm, and 1 patient who was 10 cm. Since women in their 40s and 60s were supposed to stand 40cm on one leg as a guideline, it was considered that their target patients had slightly reduced leg strength. The 2-step value is 1.28 ± 0.2, and since the average value of women in their 40s and 60s is 1.45 to 1.49, it is considered that the target patient has a slightly reduced mobility. It was. Locomo 25 was 10.3 ± 10.8 points, and the individual difference was large.

(3-3)牛車腎気丸治療後の評価(全体)
図16に牛車腎気丸治療前後の体重、BMI、脂肪量、筋肉量の評価結果を示した。いずれの項目も有意な変化は認められなかった。
図17に牛車腎気丸治療前後の握力(左右)、2ステップ値、ロコモ25の評価結果を示した。右握力および2ステップ値の有意な改善が認められた。左握力も改善傾向が認められた。一方、ロコモ25については、明確な改善が認められなかった。
(3-3) Evaluation after treatment of oxcart nephricle (total)
FIG. 16 shows the evaluation results of body weight, BMI, fat mass, and muscle mass before and after the treatment of Goshajinkigan. There was no significant change in any of the items.
FIG. 17 shows the evaluation results of grip strength (left and right), two step values, and locomo 25 before and after the treatment of the oxcart kidney testicles. Significant improvements in right grip strength and 2-step values were observed. The left grip strength also improved. On the other hand, no clear improvement was observed for Locomo 25.

(3-4)牛車腎気丸治療後の評価(著効例)
8例の対象患者中、著効を示した患者(第4症例、74歳女性)の評価結果について以下に説明する。この患者は、来院の2年前から甲状腺機能低下症としてチラージンの投与を受けていたが、甲状腺ホルモンは内服により問題ないにもかかわらず、筋肉痛が継続し改善しないため、漢方治療を希望して2013年10月31日に来院した。多発性筋炎などの膠原病の可能性を否定するために採血を行い、抗Jo−1抗体陰性であることを確認した。そこで、11月14日からツムラ牛車腎気丸エキス顆粒7.5gの内服を開始したところ、筋肉痛改善の自覚があったため内服を継続した。
図18に握力の推移を示した。図19に立ち上がりテストの推移を示した。図20に2ステップ値の推移を示した。図21にロコモ25の点数の推移を示した。図18から明らかなように、握力は右(13.1→18.5→24.2kg)、左(12.3→15.9→22.9kg)とも劇的な改善を示した。図19に示したように、投与開始前は不可能であった40cmの台から片足で立ち上がることが可能になった。2ステップ値は変化が認められなかったが(図20)、ロコモ25は順調な改善(23→18→14点)を示した(図21)。
(3-4) Evaluation after treatment of oxcart nephricle (remarkable effect)
The evaluation results of the patients (fourth case, 74-year-old woman) who showed remarkable effects among the eight target patients will be described below. This patient had been treated with Tyrazine as hypothyroidism two years before the visit. However, although there was no problem with oral thyroid hormone, myalgia continued and did not improve. I visited the hospital on October 31, 2013. Blood was collected to deny the possibility of collagen disease such as polymyositis, and it was confirmed that the anti-Jo-1 antibody was negative. Then, on November 14, I started taking TSUMURA Beef Cart Kidney Extract Granule 7.5g, and continued to take it because I was aware of myalgia improvement.
FIG. 18 shows the transition of grip strength. FIG. 19 shows the transition of the rising test. FIG. 20 shows the transition of the 2-step value. FIG. 21 shows the change in the score of Locomo 25. As is clear from FIG. 18, the grip strength showed a dramatic improvement on both the right (13.1 → 18.5 → 24.2 kg) and the left (12.3 → 15.9 → 22.9 kg). As shown in FIG. 19, it was possible to stand up on one foot from a 40 cm base, which was impossible before the start of administration. Although the 2-step value did not change (FIG. 20), Locomo 25 showed a smooth improvement (23 → 18 → 14 points) (FIG. 21).
